God might not be calling everyone of us to be the immediate Number 1 (Setman); but might have ordained some of us to be the Aron and Hur unto Moses; Joshua unto Moses; Elisha unto Elijah.
Serving the Setman is a Seed into the nearest future. If you have never serve anyone; it is possible that you might not be served very well by others.
Remember Elisha ended up with Double Portion Anointing; but Gehazi ended up with leprosy.
Also remember Korah, Dathan and Abiram (with Moses) ended up being swallowed up by the ground (miserable death).
So learn how to build up your future now - by using where you are presently as a platform to build up your capacity and proof your faithfulness unto God; so that God can then consider and then ordain you for one.
